ABSOLUTELY do NOT disassemble the rotary magazine unless you have no other choice!!!
It takes a skilled octopus (and even he wishes for a couple extra hands) and no little luck to re-assemble the magazine. DON"T DO IT!
An octopus can't put a Savage 99 magazine back together, it doesn't have a tongue to stick out the side of his mouth as he squints at the rifle.
No, seriously, the Savage 99 magazine is not really all that bad to reassemble, but it takes experience. And like my dad used to tell me, experience comes from poor decisions (in this case, taking it apart to begin with).
